Optimizing High-Power Digital Injection
Using the Shively Labs Fine-Matching Transformer

The Objective:

The analog and digital signals combine with a high degree of isolation, as shown.


The Problem:

Some manufacturers' injectors do not provide enough digital-to-analog or analog-to-digital isolation.
The output signal is distorted, as shown by the red arrows.


The Solution:

Simply install a Shively Labs fine-matching transformer between the injector and the dummy load.
Adjust the transformer to correct the output signal!
